If you're full-time self-employed
You can add simplified working from home expenses that relate to your self-employment as a manual transaction in Earnr.
Head to the transactions tab and tap Add a transaction, then choose to Add a manual transaction.
If you're employed and self-employed
To claim working from home expenses on your employment you can do so on the tax tab. Head to the As an employee income page, there's a section titled Expenses my employer didn’t reimburse me for and within there you can enter Other expenses and capital allowances. Include your employment-related working from home expenses there.
Please note
When claiming simplified working from home expenses, you should not expense your rent or utilities (gas, electricity, water).
You can claim working from expenses on your employment or self-employment, but should never claim more than £312 in total.
How to calculate your working from home expenses.
HMRC allow you to claim up to £26 in expenses per month when working from home. To claim that rate you need to do 101+ hours of self-employed work from home. If you work 51-100 hours a month at home, it's £18, and for 25-50 hours it's £10.
Example
You worked 40 hours from home for 10 months, but worked 60 hours during 2 particular months:
10 months x £10 = £100
2 months x £18 = £36
Total you can claim = £136
